Occasionally, the user will have already computed PixelGSD independently (most often from video and aircraft measurements). Currently, users in this situation have to create GCP as an extra step for the orthorectification process.

Describe the solution you'd like A clear and concise description of what you want to happen. Add any considered drawbacks.

Enable a new feature that would allow the user to edit the PixelGSD directly. Make PixelGSD a double spinbox and add a checkbox. When checked, this SpinBox can be edited. When edited, IVyTools will bypass the other orthorectification methods (meaning, the checkbox needs to add a new method to the rectify function(s).

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.

The current workaround of manually creating GCP (using the 2-point method) is valid, but it introduces a few extra steps.

Teachability, Documentation, Adoption, Migration Strategy If you can, explain how users will be able to use this and possibly write out a version in the docs or SOPs. Maybe a screenshot or design?
